, FRANCIS H. RICHARDS, OF SPRINGFIELD, MASS., ASSIGNOB TO THE AMERL CANBUTTON FASTENER COMPANY, OF NEWV BRITAIN, CONN.

STOCK FOR MAKING BUTTON-FASTENERS.

SPECIFICATION forming part of Letters Patent No. 326,152, datedSeptember 15, 1885.

Application filcd October 6, 1884. {No.modol.)

To all whom it may concern.-

Be it known that I, Fnnnors H. Rronnnns, a citizen of the United States,residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented a new and useful Improvement in theManufacture of Button-Fasteners, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof, in which- Figure 1 is a view corresponding to a plan ofthe wire as prepared for market, showing the web in a vertical plane.Fig. 2 is a side view of the same. Fig. 3 is an end view drawn inprojection to Fig. 2. Fig. 4 is a perspective View of a one'prongbutton-fastener manufactured from the wire shown in the previousfigures.

Similar letters refer to similar parts th roughout the several views.

This invention relates to an improvement in the manufacture of that kindof buttonfasteners which have a prong projecting from one side of acurved bar forming the head of the fasteners, said prong and head beingof the same width.

The object of my invention is to furnish a material from which suchbutton-fasteners may be manufactured without any waste of the same; andto this end it consists in a wire or rod having a web suitable to formthe prong and flanges to form the head of said button-fasteners, so thatthese may be made by simply cutting the said wire or rod into lengthsequal to the required width of the said fasteners.

In the drawings, A is the web of the wire, and B B the flangescorresponding, respectively, to the opposite ends, H H, of the head ofthe button-fastener F, which said ends are usually of unequal lengths,as shown best in Fig. 3. This improved wire is preferably made by firstrolling T-shaped rods slightly larger than required, cleaning thesurface of scale, and then finishing them to size by the usual method ofwire-drawing or by rolling, and the finished wire is readily convertedinto button-fasteners by simply cutting it (with suitable shears orsaws) at proper points, as lines X Y Z, Figs. 1 and 2.

For performing that cutting operation, I

have devised a wire-cutting mechanism adapted to sever the wire by meansof shearingdies, which mechanism constitutes the subject-matter of anindependent application that I intend to file.

The web or tongue A of the rod, which is to form the prongs of thefasteners, should be soft enough to allow said prongs to be readily bentby the instruments with which the fasteners are set; but the head B BFig. 3, should be rolled thinner and quite hard, so as to be close tothe fabric and have greater strength for resisting the'pull of thebutton.

The buttonfastener, F, made from said wire is an improvement on theone-prong button fasteners heretofore used, in that the bearingsurfacesof both the head and prong are smoothly finished, the cut surfaces beingon the sides, where they do not to any material extent chafe the leatheror fabric into which they may be inserted. I make no claim herein tosaid improved button-fastener, reserving the same to constitute thesubject-matter of r another application, ber 22, 1884,.

What I claim as my invention is- 1. As an improved article ofmanufacture, the improved button-fastener stock herein described, itconsisting of a head, B B Fig. 3, concaved to correspond with the curvedNo. 146,223, filed Octohead ofa fastener, and the web A, tapered fromnear said head toward the point thereof, substantially as shown anddescribed.

2. As an improved article of manufacture, the improved button fastenerstock herein described, it consisting 3, corresponding to the head of afastener, and

of a head, B B Fig.

the web A, corresponding to the prong of a fastener, said prong beingsoft and said head being harder than said prong, and for the purpose setforth.
